D-3 MAINTENANCE D-3 DRIVE ROLLS AND GUIDE TUBES After every coil of wire, inspect the wire drive mecha- nism. Clean it as necessary by blowing with low pres- sure compressed air . Do not use solvents for cleaning the idle roll because it may wash the lubricant out of the bearing.
D-4 MAINTENANCE D-4 LINER REMOV AL AND REPLACEMENT NOTE: When you change wire size, a replacement gas diffuser is required. Use the table below to select the proper diffuser so the liner is held securely in place.
D-5 MAINTENANCE D-5 12 Remove any burrs from the end of the liner . 13. Screw the gas diffuser onto the end of the gun tube and tighten. NOTE: Be sure the gas diffuser is correct for the liner being used. (See table and diffuser stencil.) 14.

E-1 THEOR Y OF OPERA TION E-1 WIRE-MA TIC 255 INPUT LINE VOL T AGE AND MAIN TRANSFORMER The desired single phase input power is connected to the WIRE-MA TIC 255 through a line switch located on the front panel. A reconnect panel allows the user to configure the machine for the desired input voltage.
E-2 THEOR Y OF OPERA TION E-2 WIRE-MA TIC 255 OUTPUT RECTIFICA TION AND FEEDBACK CONTROL The AC output from the main transformer secondary weld winding is rectified and controlled through the SCR rectifier assembly . Output voltage and current are sensed at the shunt and output terminals and are fed back to the control board.
E-3 THEOR Y OF OPERA TION E-3 WIRE-MA TIC 255 CONST ANT VOL T AGE OUTPUT The controlled DC output from the SCR rectifier assembly is filtered by the capacitor bank resulting is a constant voltage DC output.
E-4 THEOR Y OF OPERA TION E-4 WIRE-MA TIC 255 WIRE DRIVE MOT OR AND FEEDBACK The wire drive motor is controlled by the control board. A motor speed feedback signal is generated at the motor tach and sent to the control board.
